Toxic  baits  are  an  important  tool  in fruit flies management; however, some beneficial insects  such  as  natural  enemies  can  be  impaired  by  this  technique.  

In  this  study,  the  toxicity  of  some  se-lected  baits  on  Trichogramma  pretiosum  and  Chrys-operla externa, which are important as biological con-trol agents of fruit pests, was evaluated. Materials and methods      ?    Bioassays  were  conducted  under  labora-tory conditions (temperature of 25±2 °C, relative hu-midity 70±10% and 14 h day length) and consisted on the exposure of adults to a fine film of bait (drops with ~ 4 mm of diameter). Based on either, reduction of the parasitism capacity for T. pretiosum or mortal-ity for C. externa, thebaits were grouped in the IOBC toxicity  categories. Results  and  discussion    ?    The  mal-athion-basedbaits  composed  by  the  attractants  sug-arcane molasses (7%), Biofruit® (5%) and ANAMED®are  harmful  to  both  species  based  on  reduction  of  >96% in the parasitism capacity of T.  pretiosum  and  100% mortality for C.  externa.  Toxic  baits  composed  by  the  aforementioned  attractants  with  the  insecti-cide  spinosad  added,  and  the  commercial  bait  Suc-cess® 0.02   CBare harmful to T. pretiosum, with reduc-tions on parasitism capacity higher than 87%. How-ever,  these  baits  are  relatively  selective  to  C.  externa  adults, with mortality ranging from 23 to 60%. Con-clusion    ?    Based  on  the  obtained  results,  toxic  baits  with  spinosad  are  more  selective  to  predators  and  considered  a  more  ecofriendly  option  for  integrated  fruit flies management.KeywordsBrazil, fruit flies management, biological pest control, food attractants
